Hi Team,
Customer has a Java (fat) client type of app running on IOS and Android.
The server site is Apache with PHP. This app is about streaming audio, MP3 files.
After some config changes on the Apache config, the following network behavior is noticed:
- Amount of TCP connect requests are reduced with 66% (including FIN and END)
- Amount of TCP connection resets doubles
- Amount of TCP 0-win size is more or less equal
Connection resets and 0-win sizes where mostly seen on the client site; this is before and after the config change.
Customer made the config changes in http.conf:
EnableMMAP On
EnableSendfile On
KeepAlive On
KeepAliveTimeout 15
MaxKeepAliveRequests 10
The DocumentRoot is pointing to a local, DAS volume.
Audio files are retrieved from an SMB share based on a UNC.
The results are as expected when looking at the amount of connection requests; including FIN and END. However, I’m not sure about the connection resets.
Anyone an idea about an explanation for this one?
Thanks - Will |
